As you may already know, Sprint and Motorola have a luncheon event planned for June 9 where the two companies are expected to make a product announcement. With two weeks to go before CEOs Dan Hesse and Sanjay Jha take the stage, gossip is swirling over what could come. And one of the most probable rumors predicts a dual-core Android device to be known as the Photon 4G.

Prior to press invitations being sent out early this week, Phandroid was reporting that Motorola and Sprint were working together on a handset with specifications that resemble AT&T's Atrix 4G. According to their sources, the "MB855" Photon 4G will offer consumers a dual-core Tegra 2 platform with a qHD screen in the range of 4.3 inches, but with support for Sprint 4G network. Other details could include a 5-megapixel camera, a front-facing camera for video calls, and an HDMI port.

While the two companies have collaborated on a number of Android smartphones over the years, Sprint has yet to offer a high-end Motorola device. Thus far, the upper echelon of the carrier's lineup consists of Samsung and HTC smartphones. We've known for a while now that Motorola plans to release additional smartphones with laptop dock capabilities. Perhaps the Photon 4G will be the next in line.

CNET will be in attendance June 9, where we'll bring you a first-hand account of the event.
